Title: Variable threshold correlator, for cyclically repeated signal groups
IPC: G08C15/12
Filed: 1966-03-16
Abstract: 1,090,080. Synchronizing data. C.S.F.-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 16, 1966 [April 6, 1965], No. 11594/66. Heading G4H. The n + N bits of a transmitted signal, comprising an identification signal and an information signal cyclically repeated at regular time intervals, are compared at a receiver with n stored bits representing the identification signal, an output signal from a correlator 6 (Fig. 3) indicating the degree of comparison. A comparator 7 enables an AND gate 8 whenever the signal from the correlator 6 is greater than a signal stored in a memory 11 to enable the signal on lead 5 to be stored in the memory, the correlation signal previously stored in the memory being erased. Each time a new correlation signal is fed to the memory a cyclic counter 13 is reset to zero. The counter 13 has as many stages as there are bits in the identification signal and information signal combined i.e. n + N so that if during a time interval of n + N pulses no correlation signal has been fed to the memory 11 (indicating that the receiver is probably in synchronism with the incoming data), an output from the last stage of the counter erases the memory and hence permits the correlation signal on lead 5 to be stored. If the transmitted data is in synchronism with the counter in the receiver the correlation signal passed at this time to the memory will be a maximum i.e. n.
